DIPTERA. 47 
1c). Echinomyia compascua. 
Echinomyia compascua, v. d. Wulp, Tijdschr. voor Ent. xxxv. p. 192°. 
Thorax cinereous, with black lines; scutellum piceous; abdomen shining black, third segment with discal 
and marginal macrochete; head yellowish; two genal bristles; basal joints of the antennze rufous} 
palpi yellowish, filiform. 
Length 11 millim. 
Hab. Mexico 1, Omilteme in Guerrero 8000 feet (1. Hl. Smith). 
Four males. Very like L. generosa, but differing from that species in having more 
numerous macrochete on the abdomen (there being some present on the disc of the 
third segment), and the anal segment without whitish reflections. 
1 (vp). Echinomyia diaphana. 
Tachina diaphana, Fabr. Syst. Antl. p. 308'; Wiedem. Aussereur. zweifl. Ins. ii. p. 281°. 
Echinomyia vittata, v.d. Wulp, Tijdschr. voor Ent. xxvi. p. 21°. 
Hab. Mexico, Venta de Zopilote, Rincon, Tepetlapa, Chilpancingo, Xucumanatlan, 
Omilteme (H. H. Smith), Tuxpan (coll. Bellardi).—Souta America! ?, Argentina °. 
Several specimens, mostly males. They agree with £&. vittata, v. d. Wulp, which is 
inseparable from £. diaphana (Fabr.). 
Echinomyia analis (p. 33). 
To the localities given, add:—Mexico, Jalisco, Tepic (Schumann), Mexico 
city, Orizaba, Rincon, Chilpancingo, Atoyac, Teapa (H. H. Smith), N. Yucatan 
(Gaumer). 
Echinomyia nigrocalyptrata (p. 33). 
To the locality given, add:—Mexico, Atoyac, Teapa (H. H. Smith), N. Yucatan 
(Gaumer). 
Specimens of both sexes of this species have now been received from Mexico. 
In some of them the third antennal joint is not black, but of the same rufous colour 
as the basal joints (transitions, however, to the normal form prove that this character 
has no specific value). Except for the usual sexual differences (a broader front, short 
foot-claws and pulvilli, &c.), the female is very like the male; it has the front tarsi 
slightly dilated. . négrocalyptrata may be distinguished from Z. analis (Fabr.) by 
the blacker thorax and scutellum, the stouter palpi, the dark tegule, and the less 
shining abdomen, the latter without whitish or greyish reflections on the anal segment. 
Amongst the additional material I have found some males which seem to be inter- 
mediate between these two species.
